BP or Shell
Which fuel is better or are they equally the same?
|
Neither!
Tesco is better and cheaper :thumb: lol |
Shell FTW
|
Shell
Shellvpower is 99Ron
Bp ultimate is only 97Ron Tesco momentum is also 99 |
Shell V-Power would appear to be the best for your car according to what people say, however finding concrete information about the fuel is quite difficult. Shell's marketing is full of crap imo, trying to impress people with pictures of Ferraris and giving NO information about the fuel at all.
Tesco 99 is fuel mixed with bioethanol to up the octane rating, I think older versions of the Shell stuff have been the same but someone I know has suggested the latest Shell V-power is a true 99-ron petrol. The BP stuff is 97 RON and afaik this is not enough for turbocharged Impreza models regardless of what is stated on the inside of the filler cap. |
I've always used tesco momentum 99 and never had a problem. Plus you can use your club card and double up the points so it keeps the Mrs happy lol
|
Shell 99ron fuel is best.
Tesco stuff Is also fine according to tuners I've spoken to. Avoid the other brands. |
I have used all 3 when I had a DC5 and it ran badly on Tesco's, however the difference between BP and Shell was surprising V-power made it quieter and more responsive.
Since then i have always run V-power. |
I've never been a fan of tesco fuel, or any cheap supermarket fuel to be honest.
All my 'performance' cars have been run on shell optimax or the equivalent 99ron fuel they sell. |
First choice:- V power nitro plus
Second choice:- tesco momentum (only if nowhere near a shell) Third choice:- piss in my tank Fourth choice:- bp (would be further down the list but you get the point) |
In order of preference for an Impreza
1. Shell V power 2. Tescos 99 3. Esso SUL . . . 99. Coal 100. BP Ultimate :D |
This is pretty empirical / concrete!
|
Tesco 99 is like rocket fuel for me, both the Impreza and the old S3 Golf ran much quicker and cleaner on it compared to Shell.
But I mapped for Shell as there are more Shell stations around. |
Avoid BP Ultimate unless it's an emergency eg you're about to run out of fuel, but then resist using too much boost.
Just about every mapper will tell you to avoid the stuff. JohnD |

No its not. The supermarket fuel was ordinary unleaded and not super unleaded as it was called back then :)

Oh and check out your local Tesco and Shell and you will see Tesco is cheaper :D lol |

So why is bp ultimate so bad?.
|
SHELL:thumb:.SJ.

Will a car using 99 that was mapped for 97 be even safer than a car mapped for 99 that is using 99?

A car is mapped for specific fuel. Map it for one, fuel it with another and what can you read from a dyno ? The only difference would be if one was actually, say 98.7 RON and the other was 99.2 or whatever. I can't tell the difference between 0-60 in 4.0 or 4.5 tbh, and I can only 'believe' that mine runs smoother on Momentum. I can prove however that it does more mpg on it. Oh - and I'd NEVER trust Tesco with my car, yet many SN members said it would be OK - and it is. Btw - last full tank was Shell Nitro+. Haven't noticed any difference tbh. |

Silly question......
do all shell garages stock Shell V power 99? |

My understanding is that the likes of tesco add chemicals to their fuels to increase the Ron rating and quality. Hence all that issue tesco had a few years back with cars breaking down shortly after leaving the station.
For me personally, I'd rather buy from a company who specialise in fuel and oil rather than one that specialises in food but sell fuel because it's a money spinner. If I have to pay a few pence more for that privilege then so be it. I don't run my car on a tight budget so it doesn't concern me. Shell has never giving me any issues so I've no reason to change. |

However, you'd be wasting money. Ignition timing (mapping) is altered to take account of the lower efficiency of combustion (ie. the lower octane), so whatever fuel goes in the timing etc. will remain the same. It's why it's deadly to put 95 in a car mapped for, say, 99. The ignition settings are such that the fuel would pre-det. The other way around and the more efficient fuel is still ignited later, so there's no benefit. |
